Re: [Zope] automagic reindexing of objects

i make heavy use of indexes in my extension classes. these all inherit from catalogpathaware, so i have to call object.reindex_object() on each changed instance. calling it from attribute getters/setters f.ex. is not a good idea, because changing 3 attributes will reindex the object 3 times.

what i'd like to have is that such objects are reindexed automatically before comitting a transaction.

is it possible? where should i start looking in the source, is there possibly a before_transaction_commit hook?

It is impossible with "ZODB 3.2" (unless you patch "ZODB.Transaction.Transaction"). "ZODB 3.4" (which is used for Zope 2.8/3.1) has hooks that makes it possible. -- Dieter
